Color changing consumer products

ABSTRACT

The invention relates to personal care products containing multilayer films with decorative layers and may impart a noticeable color change. The invention is applicable in products including type toothpaste, soaps, and other products until diluted with water (or saliva).

BACKGROUND OF THE INVENTION

Sensory signals play an important role in communicating key benefits tothe consumer. For example, when using toothpaste there is typically noimmediate signal that the product has worked as promised or cloneanything during use. A visual cue., such as the foam changing color fromwhite to blue could dramatically improve this perception but the artreports that such technologies may not be currently feasible.

Moreover, a need exists to control the rate at which this color changeoccurs so that the signal could be used to ensure consumer compliance(e.g., to ensure a child has brushed adequately).

BRIEF SUMMARY OF THE INVENTION

The invention includes a composition that includes a film. The film iscomposed of a first shielding polymer layer, a middle decorative layer,and a second shielding polymer layer. The first and the second shieldinglayers obscure at least a portion of the middle decorative layer.

Also included are methods of using the compositions in an oral care,personal care, or home care regimen.

DETAILED DESCRIPTION OF THE INVENTION

As used throughout, ranges are used as a shorthand for describing eachand every value that is within the range. Any value within the range canbe selected as the terminus of the range. In addition, all referencescited herein are hereby incorporated by reference in their entireties,in the event of a conflict in a definition in the present disclosure andthat of a cited reference, the present, disclosure controls.

The invention broadly encompasses oral care compositions, personal carecompositions, and home care compositions. Oral care compositions includecompositions such as toothpaste, personal care compositions include suchthings as lotions and shower gels, and home care compositions includesuch things as all-purpose cleaning solutions and dish detergents. Otherexemplary compositions are disclosed elsewhere herein.

The invention also encompasses an oral care composition that includes afilm. The film includes at least a first and a second shielding polymerlayer and a middle-decorative polymer layer that is placed between thefirst and the second shielding layers. The oral care composition may bein any form, including toothpaste, a gel, a mouthrinse, a lozenge, afloss, a tooth tape, a ship, a confection, or a varnish.

The shielding layers, of which there are at least two, serve to obscurethe visual aspect of the decorative layer(s), such that prior to contactwith and/or mechanical manipulation in the oral cavity, the true visualaspect of the decorative layer is not apparent. By “obscure” it isintended to include shielding layers which presence over the decorativelayer and/or which subsequent absence alters the visual aspect of thefilm and/or the overall composition. For example, the shielding layersmay be opaque and visually shield the decorative layer; the shieldinglayers may be translucent or transparent but colored, so that theabsence of the shielding layer results is a perceived color change ofthe film; the shielding layers may even be clear, if, the decorativelayer contains a component that changes color when exposed to the oralcavity (by removal of the shielding layers), such as a pH or temperaturesensitive agent. Alternatively, the shielding layer may be shielding acompound agent in the decorative layer, that, upon release alters anaesthetic of the overall composition, such compound(s) or agents may bevisually discernable or not within the decorative layer.

The shielding lavers may discontinuous or they may provide coverage forthe entire area of the decorative layer. The film may contain more thanone decorative layer.

The diagram below further illustrates this material, which may beprepared by sequential casting of film slurries or by any other mannerin the art.

In one embodiment, the shielding layers comprise at least hydroxypropylmethylcellulose (HPMC), glycerin, and titanium oxide. In anotherembodiment, the shielding layers comprise at least HPMC, glycerin, andtitanium oxide. In another embodiment, the middle decorative polymerlayers comprise at least HPMC, glycerin, and a pigment. In certainembodiments, a pigment of the decorative middle layer is red, blue,green or mixtures thereof, but any color is suitable. A composition maycomprise more than two shielding layers.

In an embodiment, any of the polymer layers may comprise hydroxylpropylcellulose (HPC). Any of the polymer layers may comprise one or more of apigment, FD&C color, and lake color, and various color-Impartingcompounds, among other things.

The oral care compositions can include various ingredients such as atleast one abrasive, at least one fluoride source, at least one agent toincrease the amount of foam, at least one surfactant, at least onevitamin, at least one polymer, at least one flavoring agent; at leastone enzyme, at least one humectant, and/or at least one preservative andcombinations thereof.

The invention also encompasses a method of apprising a user ofcompletion of teeth brushing including applying an oral care compositionas described herein comprising a first shielding polymer layer, at leastone middle decorative polymer layer, and a second shielding polymerlayer, wherein the first and second opaque layers collectively concealat least a portion of the at least one middle decorative layer to theteeth, brushing the teeth and oral care composition to cause a foam,observing a distinct color change in the oral care composition. Incertain embodiments, the color change is in the overall composition orin the foam produced by use of the composition.

For example, when the formulations are used In the normal manner, thefilm rapidly dissolves, allowing the colorant or pigment to becomeincreasingly prominent. Foam changes color from white to decorativewithin one minute. This effect can also be illustrated by the change ofa 1:3 slurry of toothpaste in water from white to decorative as metoothpaste Is distributed and the film dissolves. The degree of colorchange can be easily changed by increasing or decreasing the quantity offilm in the formula.

Layer 3was cast at 3 mil and the final composition dried at 100° C. for another10 minutes. The films appeared white to off-white. When cut into smallpieces and formulated in a toothpaste (formula below).

Example 4 Full Toothpaste with Color Change Film

Examples 4 illustrates an illustrative embodiment showing a fulltoothpaste of a multi-layer color change formula.

When the full formulations are used in the normal manner, the filmrapidly dissolves, allowing the colorant to become increasinglyprominent. In the illustrative example, foam color changes from white todark blue within one minute. This effect may be illustrated by thechange of a 1:3 slurry of toothpaste in water from white to blue as thetoothpaste is distributed and the film dissolves. The degree of colorchange can be easily changed by increasing or decreasing the quantity offilm in the formula.

Other colors or effects are easily substituted, by replacing thepigments in the above example:

The color change may be from a white composition to a coloredcomposition. However, it will be understood that the color change mayalso be from one color to another. In some embodiments, a subsequentcolor can supplant a previous color. In other embodiments, a subsequentdifferent color may result from combination of a second pigment beingcombined with a first pigment.

For example, a different colored base, such as a light green base, canbe combined with white-blue-white triple layer film in the toothpaste.The color change will be from green to blue.

In another example, instead of the white-colored-white film set forthabove, a triple layer film can have one color in the outer layers (i.e.,layers 1 and 3), and another color in middle layer. For example, acomposition may have a yellow-blue-yellow film scheme. The triple layerfilm appears yellow, but the resultant foam will change color to blue orgreen (upon the mixing of the yellow and blue layers).

In other illustrative embodiments alternate film formulations wouldensure stability and dissolvability with use. Tuning the dissolving andrelease could be easily done by Increasing the thickness of therespective layers.
